Engineering Selection Recommendations
Both the TPS54310MPWPREP and TPS54310PWPR are Active products from Texas Instruments' SWIFT™ series with identical electrical specifications, package configuration, and regulatory compliance. The devices are functionally interchangeable for applications requiring buck regulation with 3A output capacity and adjustable output voltage between 0.891V and 3.3V.
The primary difference is the operating temperature range: the TPS54310MPWPREP supports -55°C to 125°C, while the TPS54310PWPR operates from -40°C to 125°C. Selection between these parts depends on the specific thermal requirements of the target application.
Both parts maintain ROHS3 compliance, REACH unaffected status, and identical MSL 2 ratings, ensuring consistent supply chain and manufacturing process compatibility.
Frequently Asked Questions (FAQ)
Q: Can TPS54310PWPR replace TPS54310MPWPREP in all applications?
A: The TPS54310PWPR is electrically and functionally equivalent to the TPS54310MPWPREP. The only difference is the minimum operating temperature: -40°C versus -55°C. Substitution is valid for applications operating above -40°C.
Q: Are the packages identical between these parts?
A: Yes. Both parts use the 20-PowerTSSOP package with 0.173" width and 4.40mm dimensions. PCB layout and footprint are identical.
Q: Do both parts have the same switching frequency?
A: Yes. Both the TPS54310MPWPREP and TPS54310PWPR operate at 350kHz or 550kHz switching frequency with synchronous rectifier topology.
Q: What is the significance of the MSL 2 rating?
A: MSL 2 indicates a 1-year moisture sensitivity level. Both parts require standard moisture control during storage and handling to maintain reliability.
Q: Are there any compliance differences between these parts?
A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8542.39.0001.
